Windows process creation logs show a PowerShell-driven file transfer to an FTP service. Which executable was leveraged to perform this exfiltration?

On a Linux system, review process execution records for any shell process that set an environment variable containing executable code and then piped it into another shell instance. Determine which environment variable name was used to store the script content.

On a Linux endpoint, process events reveal a chain of group‐enumeration utilities executed by a single session. Which utility was used to query the system’s group database?

A Windows system shows a cmd.exe process spawn that appears to have been used for environment discovery. Review the process creation records to identify the exact command the adversary ran to enumerate environment variables.

A user‐space process on a Linux device invoked a shell to capture and display the system’s environment variables and path. Which exact command was used to perform this discovery?

A Windows host logs a change to the Terminal Server registry key disabling single-session per user. Which command-line utility executed this registry modification?

Evidence shows that the Windows Defender startup entry was tampered with via an elevated command prompt. Investigate registry events related to the Run key to discover which executable replaced the default SecurityHealth value. What is the name of the new program?

Windows systems may be probed for their password policy settings using a native command-line tool. Determine which command was executed to list the local password policy on the target hosts.

A Windows host shows a suspicious registry change under the LSA hive. Review recent registry events to locate any new entries under Authentication Packages and determine the name of the DLL the attacker added.

A Windows host shows a process launching with install-driver switches, likely signaling malicious driver deployment. What is the name of the tool that was executed?

A Linux system shows a 'find' command used to search within .aws directories. Which specific AWS credential filename was the attacker attempting to locate?

On Windows systems, identify any user account that was hidden by setting its value to 0 under the SpecialAccounts\\UserList registry key. What was the name of the hidden account?

Identify the PowerShell cmdlet used on Windows to format and display the raw volume bytes after an attacker read the boot sector via a DOS device path.

In a Linux environment, an elevated process was used to execute a command that read /etc/shadow and redirected its output to a file. Identify what file name was employed to store these results.

On a Windows host, someone appears to have run a built-in network shell utility to list saved wireless network profiles and their passwords in clear text. Review the process creation logs to discover the exact command that was executed.

Review Linux process execution records for any commands that list TCP metric cache entries and filter out loopback interfaces. Which utility was used?

A Windows host shows a process launch with an extremely obfuscated command line that dynamically builds and invokes code at runtime. Which process name was used to execute this payload?

A process is running under a familiar Windows host name but originates from a user's AppData folder rather than the System32 directory. Identify the filename used to masquerade the PowerShell binary on this Windows device.

A threat actor on a Windows system crafted and registered a service named almost identically to the standard time service, but redirecting execution to a custom script. Review the logging data to determine which native command-line tool was used to perform this action. What utility was invoked?

Analyze Windows process events for any schtasks.exe commands that created a new task invoking PowerShell. What is the name of the .ps1 script specified to run?

Linux hosts may log events when new files are added to /var/spool/cron/crontabs. Query those logs for a creation or write action in that directory and determine the file name that was added.

You suspect malicious persistence via scheduled tasks on a Windows endpoint. Review the process execution logs to identify the built-in utility used to register tasks at logon or startup. What is the name of this utility?

On a Windows device, review the process execution logs to find instances where a built-in listing tool was piped into a string filter. Identify the process name that the attacker was searching for.
